How are convertible bonds treated in computing diluted shares when determining Equity Value?

• A. Convertibles are counted using the Treasury Stock Method.
• B. Convertible bonds are ignored.
• C. If in-the-money, count as equity; if out-of-the-money, treat as debt.
• D. Convertibles are always counted as cash.

Answer: (C)

When computing diluted Equity Value, the key idea is whether converting the instrument would actually dilute shareholders. A convertible bond is counted as equity only if converting it would increase the number of shares outstanding in a way that people would implement it—the in-the-money situation. In that case, you add the potential shares from conversion to the equity base. If converting isn’t advantageous (out-of-the-money), holders wouldn’t convert, so there’s no dilution and the instrument stays as debt in the calculation. This is why counting convertibles as equity only when they’re in-the-money, and treating them as debt otherwise, is the correct approach. For context, the treasury stock method is a different technique used mainly for options and warrants, not convertibles, which is why it isn’t applicable here.
